Work scalar ?

Hi, I'm a bit confused on how 'work' can be scalar. I understand that W=FSCosX where X is the angle between the point of application of force and the object. So if the Work depends upon the angle, shouldn't that mean it depends on direction of force applied making it a vector? I'm a high school student so please don't kill me because I'm honestly confused.

Force is a vector (3D). The "difference" from point A to B can be called a vector (d=(x1,y1,z1)-(x2,y2,z2)). Between, there is a so called scalar product. Meaning:
Fx * dx + Fy * dy + Fz * dz = W (Work). Do you understand that the scalar product between vectors is a number and in this case: Work is scalar?
If not, try in mind to move a body where you live. Take the body and have a nice trip to Regensburg in Germany. Move the body there (cheaper to do it in your neighboorship but nevertheless a nice journey). The energy you will spend is the same. And the direction is not important, there is no east or west or north or south energy.

F.Scos x=W
S is displacement i.e. a vector quantity
i.e.
Scosx is also a vector
F is force i.e. a vector
u must remember that the dot product of two vectors is scalar
thus W=F.S cosx is a scalar quantity

if you look at the two lines above, the dot product is like asking how much the top line lays over the bottom line. As you change the angle between the two lines, you will have different lengths of overlap (the "projection" it's called, since you're essentially measuring the length of the shadow the top line casts on the bottom line). No direction required to answer that question.

Okay so the product of two vectors is scalar and thus Work is scalar. Am I right?

Can I check that the right question was (already well) answered?

Are you asking why work (i.e. *energy*) is a scalar, or are you asking why 'FSCosX' is a scalar?
